Assessment of aortic stiffness and ventricular diastolic functions in patients with Behçet's disease

Behçet's disease is a systemic vasculitis in which studies have given conflicting results about ventricular diastolic functions. However, tissue Doppler echocardiography has never been used in any of these studies. Aortic stiffness, a cardiovascular risk factor, may also precede ventricular dysfunction. The aim of this study was to assess aortic stiffness and biventricular diastolic functions in patients with Behçet's disease. A total of 26 patients with Behçet's disease (mean age; 33+/-10 years) and 20 age- and sex-matched controls (mean age; 33+/-7 years) were included. Aortic stiffness was evaluated by aortic strain and distensibility. Ventricular diastolic functions were evaluated with both conventional and tissue Doppler echocardiography. Mitral E and A wave, E/A ratio of E wave, deceleration time, and isovolumic relaxation time were calculated. There was no significant difference in diastolic Doppler parameters between patients and controls. Similarly, there was no significant difference in mitral annular E and A velocities between these two groups. Aortic strain in patients with Behçet's disease was found to be significantly less than in the controls (8.3+/-4.9% and 15.7+/-2.7% respectively, p
